Anthurium platyrhizum Croat

Epiphyte; stems very short, green; leaf scars ca. 8 mm wide; roots dense, greenish brown, flat, 5-8 mm wide; cataphylls coriaceous, 1.5-3.7 cm long, drying brown with a raised medial rib, acute and apiculate at apex, the apiculum ca. 1.5 mm long, drying tan (B & K Yellow 6/5), splitting at base, intact at apex, subpersistent. LEAVES spreading; petioles 4-11 cm long, 2-3 mm diam., weakly flattened to shallowly sulcate adaxially; geniculum 1-1.7 cm long; blades narrowly elliptic to oblanceolate-elliptic, acuminate at apex, acute to obtuse or rounded at base, 17-30 cm long, 4.3-8.7 cm wide, broadest at the middle; upper surface matte to semiglossy, lower surface semiglossy; midrib weakly raised at base above, diminished and sunken at apex, prominent and convexly raised below; primary lateral veins 4-6 per side, departing the midrib at 45-55° angle, flat to weakly sunken above, nearly obscure in older leaves, prominulous below, more or less straight to collective vein; lesser veins obscure above, flat below; collective vein arising from near the base, sometimes extending along midrib at base for up to 2 cm before branching out to form collective vein, 0.4-1 cm from margin, sunken above, raised below. INFLORESCENCE spreading, usually shorter than leaves; peduncle 10.5-26 cm long, 2-3.5 mm diam., terete, 2-5 times longer than petioles; spathe subcoriaceous, green (B & K Yellow-green 6/7.5), ovate 2.6-4.5 cm long, 1.5-2 cm wide, broadest just below middle, abruptly acuminate at apex, rounded to acute at base; stipe pale green, 1-1.7 cm long, 2-4 mm diam.; spadix dark green (B & K Green 5/2.5), scarcely tapered at apex, 1.6-3.5 cm long, 5-8 mm diam. midway, the flowers 4-lobed, 4-4.5 mm long, 5-5.5 mm wide, the sides jaggedly sigmoid, 3-4 flowers visible in the principal spiral, 4-5 flowers visible in the alternate spiral; tepals glossy with obscure, pale punctations, minute droplets apparent at anthesis, lateral tepals ca. 2 mm wide, the inner margin weakly rounded; pistils emergent ca. 1 mm, whitish, translucent, pointed, sometimes tinged violet purple near edges of tepals; stigma broadly elliptic, 0.5-0.6 mm long, with small clear droplets apparent 1-2 days before stamens emerge; stamens emerging beginning from the base, laterals first, emerging to midway before alternates emerge, exserted on short, translucent filaments, retracting and held at edge of tepals in a close but non contiguous circle around pistil; anthers yellow, ca. 0.6 mm long, 0.5 mm wide; thecae oblong, slightly divaricate; pollen bright orange fading to pale orange to tan. INFRUCTESCENCE with berries ovoid, ca. 8 mm long, 4 mm diam., violet purple, rounded at apex; seeds not seen.
